Method of manufacturing three dimensional image display device

A method of manufacturing a three dimensional image display device, comprising:

• applying an adhesive member to any one of a lens plate including a lenticular lens, and a display panel configured to display an image, the adhesive member applied to form a continuous frame having an application height higher than a separation distance between the lens plate and the display panel in a bonding complete state;
• measuring the application height of the adhesive member thus applied;
• figuring out a volume of an enclosed space, which is formed by the display panel, the adhesive member and the lens plate, by using a lowest application height of the adhesive member thus measured, and figuring out a bonding pressure leading to obtaining of a necessary internal pressure in the enclosed space, by using the volume of the enclosed space thus figured out;
• and
• bonding the lens plate and the display panel together by use of the adhesive member, with the display panel and the lenticular lens facing each other, in a reduced pressure atmosphere with the figured-out bonding pressure.
